' To all'whom it may concern:

OLoIsE H. BALDWIN, a residing at Erie, in the county of Neo'sho and State of Kan sas, have inventedcertain new and use Im rovements in Explosive-Engines, of

- In the accompan' 'ng drawing illustrating the preferred embodiment of my invention- Figure -1 is a sectional elevation thereof. Fig. 2 is an end view of the same. Fig. 3is a side view, showing more articularly the piston together with its r0 er-bearing and springs. Fi or motor, an Fig. 5 is a detached view showing more es ecial y the piston-actuating cam.

In the disclosure of my invention, Isu port in elevated position, in any suitab e way by an upright frame a, or otherwise, the water-jacketed cylinder 1, having arranged therein the usua piston 2, only one being employed herein and which has fixed to it arallel bars or arms 3, between which is ung or journaled a roller 4, having its periphery prcgecting beyond one end of said cylinder. arms 3 have fixed thereto a cross-rod 5 to which are suitably secured cross-head like members 5 through which extend guide-rods 6 suitably fixed to a s tpplemental support gul e-rods form sup-. helical or coiled springs which are effective to exert pressure upon and thus proor frame I). Said 7 the cross-head like members 5" vide for maintaininghefiective contact or enagement between t e roller 4 and the drivresently described.

A driving s aft 8 is suitably 'ournaled upon the su plemental bearing and in practice suita y equipped for transmitti power or motion to the part to be operate 4 is a plan view of the engine aid roller equipped or carrying by the engine or motor, and which shaft has for its actuation by the fixed thereto a cam 9 piston 2 when under gas pressure, as.w1 e readily appreciated. Said cam has 'two practically elliptical cam-surfaces or arms 10, 11 upon op osite sides of its axis, which is formed by t ever, are of unequal length and which cam has also opposite concaved surfaces 12, 13

intermediately of said elliptical cam-surfaces 10, 11, the function of all of which will latera pear.

In t e head 14 of the cylinder 1' are arranged or applied as shown, the sprin -seated inlet-valve 15, the spring-seated e austvalve 16 and the electric igniter or plu 17, preferably of the jum spark type, w 'ch are all well known in t 's art,

The ordinary centrifugal type of governor is suitably located and connected as shown in the usual-way with the engine or motor shaft, as well understood, for s eed-control.

The 0 eration is as follows: ssuming the parts to e in the position illustrated in Fig. 1, the longer cam 10 has forced the piston its full outward stroke thus clearing the cylinder of all exhausted gases. The further rotation of the shaft 8 permits the piston to move inwardly thus suckin in an explosive charge. With the half comp etionof a revolution of the shaft 8 the shorter cam 11 returns the piston part way on its outward stroke, therecom ressing" the mixture between it and the hea of the cylinder just prior to the exlosion. The ex losion now takes place and as the effect 0 forcing the, piston inward and impartin a new rotary impulse to the shaft, and-wit the return of the longer arm 10 of the cam, cylinder is again scavenged of the exhaust gases, plete cycle.

.This invention is devised to be used as a motor using ex losive products, such as gasolene, gas, alco 01, na htha and all other roducts combined wit air, forming an explosive mixture, in other words an explosive on me.

he piston actuating cam takes the place of the ordinary engine crank or shaft. The stroke of the short arm of the cam is about two-thirds of the stroke of the longer armor thus completing a come'shaft 8, which arms, howof such length that the arms of the cam with shorter throw is sufiicient to allow for com- 5 ression space; the longer arm of cam ejects all of the previously. burned charge.
